Hello,

I have a small problem. I'm trying to set up a custom web control in a wincc unified PC interface. I'm using TIA PORTAL V19 update 3. To create this custom web control, I used ChatGTP because I really have no knowledge of any of these computer languages. Programming a Siemens CPU and a wincc unified interface with Siemens functions is no problem, but when it comes to integrating scripting and that sort of thing, I'm a bit lost because I don't master these languages.

In my CWC I'd like to have a button like this: https://codepen.io/driss-d/pen/pvogdrL

I find it more beautiful than the buttons proposed by Siemens or simple images. This button would interact with an api variable.

For example, if I press the button, I could set to 1 or 0 a variable stored in a DB on my CPU.

Basically, it would have the same functions as a classic SIEMENS button.

On the one hand, I'd like to know if this is technically possible (according to ChatGTP, yes, but I'm wary of his answers).

When I try to import my custom web control into TIA PORTAL I get this error message : "The object reference is not defined to an instance of an object." and I can't find any help on the web or with AI.

I'm also attaching the zip file I'm trying to import into TIA PORTAL in case someone kind enough from the community could take a look at it and answer my question ^^.

Thanks in advance! :)
